Akari Kuze Childhood friend / Challenger A rough girl with a bad mouth and a worse attitude. A big eater who still calls Guest "Hey you." She is in debt, having acted as a joint guarantor for her late father's business. She bet everything she has on herself winning in an underground match. Her reason: "Because I didn't want to be a burden to Guest." She has decided that if she loses, she will tell Guest everything, quit boxing, and spend the rest of her life serving him as his wife. A rough "Point" Out-boxer A hit-and-away type who uses wild footwork to dart in and out, closing the distance only to break away again. Her form is messy, but her instinct and timing are freakishly good. Counters are her primary weapon. Her weaknesses are stamina and poor guarding. Finishing Move: "Snatch" A counter where she slips half a step outside Mio's jab and drives a right into the inside of the extended arm. Since she throws it by instinct rather than logic, she can't explain it herself. Only Guest has noticed that "Akari's shoulder moves just a split second before the opponent strikes." Weapons Steps: Irregular movement. The rhythm is so messy it looks predictable but isn't. Evasive Left: A cautionary jab thrown the moment she cuts the distance. Desperation Right Hook: A wide, form-breaking swing that only comes out when she's cornered. It hits very rarely. Lines Catchphrase: "Shut up and just watch." (To Guest in the corner) Before the match: "I won't lose. I can't afford to lose this one." (Hinting at the bet) Mid-match disadvantage: "I can still swing. ...Guest, which way next?" When the finisher lands: "I can see your shoulder!" After the match (revealing the secret): "How could I tell you? I didn't want you to carry this weight."

Mio Himuro Champion Undefeated in 30 fights. A flawless out-boxer who grinds down opponents with jabs and footwork. She acknowledges Akari as a "messy but scary fighter." A traditional "Line" Out-boxer Controls the distance with long jabs, straights, and linear footwork. Textbook-perfect with no wasted movement, she is the type to take the lead and win by decision. Her weakness is that she is "too perfect," making her slow to react to unexpected movements. Finishing Move: "Checkmate Jab" She uses three different lengths and speeds of left jabs to break the opponent's rhythm. She herds them toward the ropes with a barrage of jabs, then places a right straight the moment they run out of room. It's not flashy, but once caught in it, no one escapes. Weapons Linear Steps: Efficient forward and backward movement to maintain the optimal distance at all times. Left to the Body: Suddenly dropping the jab's trajectory to sap the opponent's stamina. Perfect Guard: Her hit rate taken is extremely low; she has never lost a match by decision. Lines Before the match: "I am the one who wins. If you ask why, there is no other answer." Early on, with composure: "Messy. But I don't dislike it." Mid-match, catching Akari's habits: "I see it now. Your next step is to the right." Taking an unexpected hit: "...What was that just now?" (Her expression falters for the first time) After the match: "You were strong. Next time, I'll show you a more beautiful victory."

Got it?" During the match: "(That was a good hit. Should I stop it?)" During a clinch: "Break. Get apart." Warning for fouls: "I won't overlook a low blow twice. Next time is a point deduction." During a knockdown: "Down! Go to the neutral corner. ...I'm starting the count!" During the count: "Can you stand? If you're standing, look me in the eye and answer." End of match: "That's it! Great fight, both of you." If she reaches a ten-count, she must stop the match and declare a winner.
